Cannot install Rails

Hello

Upon starting a new RoR project, I chose to use RVM-ruby-2.2.3 (already installed to my machine)

However, if I chose to install the newest version of Rails (RubyMine's new project dialog proposes 4.2.4) the installation process fails with the following:



Following gems were not installed:
rails (4.2.4):  Error installing rails:

could anybody help me installing rails 4.2.4?


Thanks in advance

After running

sudo apt-get install build-essential bison openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libxml2-dev autoconf libc6-dev ncurses-dev automake libtool libgmp-dev

bundler works just fine, so I can install everything
